Ruin

"Ruin" was a notorious villain in Bianco City and in Europe, the benefactor of the Hive of Villains and the archenemy of Peterson Richards/All Master.

Once Europe's most powerful villain and All Master's archnemesis, his true motives and identity are still unknown and was defeated by All Master. Surviving and creating the Hive of Villains, he targeted Bianco Academy. In a final battle with his nemesis, Ruin was defeated once again and killed, with the Hive of Villains disbanding.
